High-probability broadband signal accurate measurement system and method

Abstract

The invention discloses a high-probability broadband signal accurate measurement system and method. The system comprises a radio frequency power divider with two output ends, a broadband receiver, a time cache module with n output ends, n radio frequency conversion units and n narrowband receivers, wherein the two output ends of the radio frequency power divider are respectively connected with theinput ends of the broadband receiver and the time cache module; the output end of the broadband receiver is connected with each radio frequency conversion unit and each narrowband receiver; and the noutput ends of the time cache module are connected with the n narrowband receivers in a one-to-one correspondence manner through the n radio frequency conversion units. The method guides narrow-bandsignal receiving processing with broadband, in combination withthe broadband signal time caching technology, solves the problem of accurate time matching receiving of the narrowband receiver and the broadband receiver, and on the basis that it is guaranteed that signals are not lost, achieves the high-sensitivity, high-precision and real-time parameter measuring capacity on various types of broadband signals.

Description

technical field [0001] The invention relates to the field of broadband radio frequency signal detection, in particular to a system and method for precise measurement of high-probability broadband signals, which can be used for high-precision and rapid extraction and measurement of radio frequency signal parameters in electronic equipment such as radio frequency spectrum monitoring and target reconnaissance. Background technique [0002] Electronic equipment such as radio spectrum monitoring and target reconnaissance must analyze and identify the characteristics of radiation sources by receiving and processing radio frequency signals from the outside world, so as to obtain accurate electromagnetic spectrum situations. Since the radiation source is a non-cooperating object, the number of targets, signal types and parameters will have uncertain distributions in a wide range of instantaneous frequencies. Especially on the basis of the development of digital signal processing, pa...
